Patent CA-2171792-A1 (CA)
Inventor: KVALHEIM ANDREW M
IPC: E06B3/984
Filed: 1996-03-14
Abstract: A method of making a joint, and the joint thereby produced, in which a first element comprised of low cohesion material is joined to another element of a structure, at a position at which opposed surfaces of the first element and the other element are adjacent and generally abutting, by driving at least one nail through the first element and into the other element at a nailing point at said position. Prior to driving the nail, a nailing cavity is formed adjacent the abutting surfaces at the nailing point that extends outwardly therefrom in the direction of the surfaces and that extends a substantial distance normal to the nail direction. The nailing cavity minimizes fracture of the low cohesion material and receives fractured fragments of low cohesion material that does break from the first element by penetration of the nail therethrough, thereby to prevent wedging of fractured material between the abutting surfaces of the elements that surround the nailing point which can result in a loose and insecure joint.

Abstract: L'invention concerne un procédé et un dispositif de régulation et de commande d'un système de distillation ou de condensation, comprenant un ballon de distillation (13), une source de chaleur (10) et un condenseur (8). Les systèmes de distillation ou de condensation nécessitent des volumes considérables d'eau de refroidissement qui sont dérivés régulièrement directement dans l'écoulement par l'intermédiaire d'un flexible raccordé au condenseur. L'invention vise à mettre au point un procédé et un dispositif de régulation et de commande d'un système de distillation ou de condensation, qui permettent de réduire considérablement la consommation d'eau de refroidissement. A cet effet, il est prévu que l'eau de refroidissement qui traverse le condenseur (8) du système de distillation ou de condensation soit guidée dans un circuit, que sa température soit détectée dans le circuit, et qu'arrivée à une température supérieure, elle soit remplacée, par apport d'eau froide, jusqu'à obtention d'une valeur de température inférieure. Dans le dispositif correspondant, il est prévu un régulateur d'eau de refroidissement pouvant être relié au condenseur (8) du système de distillation ou de condensation par l'intermédiaire d'une pompe (2), pour former un circuit d'eau de refroidissement. Il est également prévu un clapet (1) régulé par un régulateur (11) et raccordable à une conduite d'eau froide, ainsi qu'un détecteur de température (4) placé dans le circuit d'eau froide. Le régulateur pilote le clapet (1) de manière à ce que lorsqu'une température supérieure d'eau de refroidissement est atteinte, ledit clapet (1) s'ouvre jusqu'à ce que la température d'eau de refroidissement atteigne une valeur inférieure.

Title: Method and system for directory assistance services
Inventor: COX PATRICK M
IPC: H04Q7/36
Filed: 1996-06-06
Abstract: A mobile telephone, or personal communication services subscriber who wishes directory assistance services is connected in the conventional manner to an operator who identifies a destination telephone number desired by the subscriber. As known in the prior art, the operator then initiates a call connecting the subscriber to the destination telephone number. In a preferred embodiment, the operator locates a desired destination telephone number in a computer database, and can select automatic dialing of the located number. Further, rather than dropping all further involvement with the call, the preferred embodiment of the present invention continually monitors the connection thereby established for a predetermined DTMF signal issued by the customer, such as that obtained by pressing the "*" button. If such a signal is detected, the customer is transferred to a directory assistance operator, who can then provide whatever further assistance is needed (e.g., providing further directory assistance). If a busy signal or non-answering party is detected, a customer is given a plurality of options including leaving a recorded message or page, or a predetermined alphanumeric message or page for the called party. In this case, the system automatically tries, repeatedly, to deliver the recorded message or page and, optionally, confirms successful or failed message delivery to the calling party.

Title: Method of synchronizing a pair of central processor units for duplex lock step operation
Inventor: SONNIER DAVID PAUL
IPC: H04L69/40
Filed: 1996-06-06
Abstract: A method of synchronizing a pair of substantially identical processors for substantial lock-step operation is disclosed.  One of the processors is operational, executing an instruction stream from a memory element exclusive to that processor; the other processor is in a wait state.  The method involves copying the instruction and data content of the memory of operating processor to the memory of the welting processor in a manner that stores the transferred instructions and data in the memory of the waiting processor at locations that correspond to where the instructions and data are located in the memory of the operating processor.  Thereafter, the operating processor will periodically send selected ones of the instructions and data to the waiting processor.
Patent CA-2178499-A1 (CA)
Inventor: SVEDMAN PAL
IPC: A61B5/00
Filed: 1994-12-01
Abstract: A housing (2) is secured to an area of skin to allow suction to be applied to a local area of skin through an aperture (6). After formation of a suction blister, a blade (18) is actuated to sever a suction cup (9) thereby detaching the means for creating suction at the aperture and at the same time removing the roof of the suction blister to expose an area of dermis from which the skin's epidermis has been removed. A rotatable portion (5) of the apparatus is then moved into a position in which a port (22) communicates with a compartment (11) within the rotatable portion. The compartment may contain a reservoir of fluid substance to be transdermally absorbed or may contain means for taking a sample of exudate produced at the exposed dermis. A modified apparatus has means for applying suction to the exposed dermis to enhance the rate at which exudate is formed and for handling a sample of exudate for analysis. Transdermal delivery and sampling are thereby achieved non-invasively and without the impediment of the skin's epidermis.

Title: A method for obtaining a one-cell reuse pattern in wireless communication systems
Inventor: DONER JOHN R
IPC: H04W16/24
Filed: 1995-10-27
Abstract: A technique for allocating frequencies in a cellular communication system. The frequency reuse plan divides all available frequencies into six groups with the frequencies assigned in an ascending index order modulo 6. A three cell reuse plan is implemented with six 60· sectorized antennas per cell, and two frequency groups being assigned for use in each cell. The channel groups are allocated to the sectors such that no two adjacent sectors use the same frequency groups. As a result, an effective times one frequency reuse plan is implemented. A frequency assignment process which attempts to avoid assigning the same frequency to amobile which is located in the outer portion of a sector which is also in use in potential interfering outer sectors of homologous cells insures that carrier to interference (C/I) ratio minimums can be met without specialized encoding techniques.
